DK and DK/CPDN 15÷65
New diaphragm valves with maximised flow rate available in manual or pneumatically actuated versions.
Manual versions are equipped with the innovative DIALOCK® lockable handwheel. Pneumatic versions may have piston or
diaphragm actuators.

DK DIALOCK® DN 15-65The new diaphragm valve with maximised flow rate and innovative handwheel
Customisation plateThe customisation lets you identify the valve on the system according to specific needs.
High visibility graduated optical position indicator protected by transparent cap with seal O-Ring.
Floating pin connection between the control screw and diaphragm to prevent concentrated loads, improve the seal and extend its lifetime.
Optimised fluid dynamic design Substantially increased flow coefficient and reduced pressure drop thanks to the new internal geometry of the body.Sensitive and precise adjustment along the entire stroke of the shutter thanks to the greatly improved characteristic curve of the valve.
Valve body set up for the installation of an identification tag.
Valve anchoring bracket integrated in the body with threaded metal inserts.

PMDK multifunction plateWith the PMDK mounting plate,
alignment of the valve axis with the rest of the system
becomes even easier. The plate also allows simple and rapid
anchoring of the valve to a wall.
Waterproof designThe special design
and components of the handwheel make
the operating mechanism totally waterproof,
isolating all the internal metal parts from contact
with external agents.
Corrosion resistantThe operating mechanism
entirely in fibreglass reinforced PP (PP-GR) and the absence of metal parts
exposed to the external environment make the
valve suitable for chemically aggressive applications.
DIALOCK® System: innovative handwheel with an immediate and ergonomic operating locking device, that allows it to be adjusted and locked in over 300 positions.

New DN65 bodyThe performance increase deriving from the new fluid dynamic design has also allowed a new DN65 body to be realised identical to the DN50, improving the flow coefficient by over 20% while retaining the installation dimensions of the traditional DN65 but with a 60% plus reduction in weight.
CDSA seal systemThe new design of the internal profiles, free of dead areas, minimises the risk of a build-up of deposits and diaphragm contamination or damage through crystallisation, leaving the inside of the valve clean and hygienic.
ADJUSTMENT LINEARITY
The work carried out on the internal profiles of the valve has also achieved the aim of greatly improving its characteristic curve, allowing extremely sensitive and precise adjustment along the entire length of the shutter stroke.

ADJUSTMENT LINEARITY AND EFFICIENCY
New maximised flow rate valve bodies
Valve bodyThe new DK series has a valve body with an optimised internal fluid dynamic design that increases performance by up to 90% with respect to previous models. The new internal geometry of the valve has, in fact, allowed its efficiency to be greatly improved, obtaining substantial increases in the flow coefficient values (Kv100) and a resulting reduction in pressure loss.The degree of efficiency reached has also enabled the size and weight of the valve to be reduced.

SAFE AND PRACTICAL TO USENew Dialock® integrated handwheel locking system
The valve can be locked by simply lifting the handwheel once the required position has been reached.
To release, simply push the handwheel downwards.
To further safeguard the system against unwanted interference, it is also possible to fit a lock after having set the handwheel in the locked position.
Handwheel and bonnet are in high mechanical strength and chemically resistant PP-GR, guaranteeing full protection by isolating all internal metal components from contact with external agents
Dialock® systemThe innovative handwheel is equipped with a patented immediate and ergonomic locking device that allows it to be adjusted and locked in any position.

MAXIMUM AND MINIMUM FLOW RATE SETTINGS
DKL series with travel stop and stroke limiter integrated in the handwheel
The DKL valve, a limited version of the DK diaphragm valve, is equipped with an innovative handwheel stroke control system which allows the maximum and minimum flow rates of the valve to be changed and prevent excessive pressure on the diaphragm during closing.The system allows the valve stroke to be modified using the two independent adjusting screws, which determine the mechanical limits of the valve during opening and closing.
Travel stop adjustmentTo set the lock to the minimum flow rate or closed position, rotate the handwheel until the required position is reached and then lock the set position by tightening nut (A) and locknut (B).
Stroke limiter adjustmentTo set the lock to the maximum flow rate, rotate the handwheel until the required flow is reached and then lock the set position by rotating knob (C) anticlockwise until it reaches the stop.

INSTANTANEOUS CHECK AND ADJUSTMENT
UNIQUE ID FOR EACH FUNCTION
PRACTICAL INSTALLATION SOLUTIONS
Graduated optical position indicator
An immediate indication of the opening percentage of the valve is provided by the high visibility graduated optical position indicator, protected by a transparent cap with seal O-Ring.The graduated scale of the indicator has 4 valve opening percentages: 25, 50, 75, 100%.Thanks to the adjustment linearity of the valve, the flow rate can be regulated intuitively by simply glancing at the indicator.
Integrated customisation plateA white PVC customisation plate is housed in the transparent protection cap, which can be removed and, once overturned, used for indicating identification serial numbers or service indications on the valves such as, for example, the valve function in the system, the conveyed fluid and specific information for customer service, such as the customer name or installation date or location.The waterproof transparent protection cap with seal O-Ring protect the customisation plate against deterioration.
PMDK multifunction plateDK valves are equipped with an integrated anchoring bracket with threaded metal inserts that allow direct fixing of the valve body without the need for additional components. This bracket allows the DK to be fitted with the multifunction PMDK plate required for simple and rapid valve mounting on a panel or wall. With the PMDK plate, it is also possible to align the axis of the valve with the FIP pipe clips. The PMDK mounting plate is supplied as an accessory.

ACTUATED DK DN 15-65A full range of pneumatically actuated versionswith piston and diaphragm actuators
Key features of the new actuator6 independent cartridge springs arranged radially to uniformly distribute the load on the piston. Dual function main gasket.Piston seal: the gasket does not move but sits securely on the actuator cylinder instead of the piston.External seal: The gasket positioned above the threaded joint between the bonnet and cylinder ensures that the coupling is notstressed by the pressure inside the actuator.
Piston in high strength IXEF The high quality finishof the external surface guarantees perfect slidability over the seal and ensures a long working life without any actuator maintenance.
High strength stainless steel stem with double seal O-Ring. Floating pin connection between the actuator stem and diaphragm to prevent concentrated loads, improve the seal and extend its lifetime.
High visibility optical position indicator protected by a
transparent cap with seal O-Ring.
DKP/CP DN 25-65 Pneumatically actuated diaphragm valve, single-acting (NC-NO) or double-acting (DA) with optimized flow rate body and piston actuator in IXEF, compact, ideal for applications requiring a high operating frequency and a long valve lifetime.The DKP/CP is available in PVC-U and PP-H versions.

When installing in confined spaces, the
connections can be oriented in line with the piping.
AccessoriesThe DK actuated valve range can
be equipped with various accessories,
such as: pilot solenoid valve,
positioners and different position
detection sensors.
DK/CP DN 15-20The new DK/CP is a pneumatically actuated diaphragm valve with maximised flow rate body and a robust and compact piston actuator in fibreglass reinforced PP (PP-GR), available in either a single-acting (NC-NO) or double-acting (DA) version. The construction characteristics of the DK/CP make it the ideal solution for applications requiring a high operating frequency and a long lifetime under aggressive service conditions and in chemically aggressive environments. The DK/CP is available in PVC-U, PP-H, PVC-C, PVDF versions.
DKM/CP DN 25-65 Pneumatically actuated
diaphragm valve, single-acting (NC-NO) or
double-acting (DA) with maximised flow rate
body and diaphragm actuator in high strength PP-GR, suitable for heavy
duty applications and chemically aggressive
